Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 5 generators on 28 points:

(2,3)(5,6)(7,9)(8,10)(11,12)(13,14,18,19)(15,20,25,27)(16,26,24,21)(17,22,28,23);(1,2,4,3)(5,7)(6,9)(8,11)(10,12)(13,15)(14,20)(16,22)(17,21)(18,25)(19,27)(23,24)(26,28);(6,10)(7,11)(13,16)(14,21)(15,23)(17,27)(18,24)(19,26)(20,28)(22,25);(6,10)(9,12)(13,17,19,23,18,28,14,22)(15,24,20,21,25,16,27,26);(1,3,4,2)(16,24)(17,28)(21,26)(22,23)
